AMD rallies as cryptocurrency miners snap up graphics chips. Business in the age of Ethereum. When Bitcoin burst onto the scene in 2009, it challenged preconceived notions about the limitations of transactions.

Fast-forward 8 years, and another platform is dominating the headlines. Ethereum has built on Bitcoin’s potential and is driving a revolution in financial transactions. Ethereum is an open-source platform that facilitates the development of next-generation decentralized applications. It was conceptualized in 2013 by Vitalik Buterin, who at the time was conducting research within the Bitcoin community.

Since Buterin’s initial ideation, Ethereum has grown in interest and scale; today it is poised to overhaul open-source development. Bitcoin opened the world to the possibilities of shared ledgers, and now Ethereum is expanding on that potential. Since Bitcoin’s debut on the world stage, many developers have sought to apply the ideology to new systems similarly underpinned by blockchain technology.

Bitcoin Breaks $1,000 Level, Highest in More Than 3 Years - Slashdot. The price of digital currency bitcoin has hit the $1,000 mark for the first time in three years.

Rakuten buys struggling bitcoin startup Bitnet to create a ‘blockchain research lab’
Rakuten has confirmed that it has acquired the assets of Bitnet, a bitcoin wallet startup it invested in, which will be used to create a ‘bitcoin lab’ for the Japanese retail giant.

The transaction is undisclosed but it follows a Wall Street Journal report in July which speculated that a deal was in the works. Rakuten took part in a $14.5 million investment round for Bitnet nearly two years ago, which was led by Highland Capital Partners. Rakuten integrated Belfast-based Bitnet’s payment option into some of its online commerce sites last summer.
Bitcoin drops 20% after $70M worth of Bitcoin was stolen from Bitfinex exchange. Bitfinex, one of the most popular cryptocurrency exchanges online, has suffered a major hack.

The company has posted a note on its website detailing the security breach, and while it doesn’t mention a total amount, one of their employees confirmed on Reddit that the total amount stolen was 119,756 bitcoins. That amount converts to about $77,000,000 based on a price of $650 USD per bitcoin, which is about what bitcoin traded at over the course of the last week. After news of the hack spread, the price of bitcoin dropped almost 20 percent, settling in around the current price of $540 USD per bitcoin. It’s not exactly clear why the price dropped, but it’s likely bitcoin investors got nervous about potential hacks on other exchanges and decided to sell off their bitcoin holdings, which led to a rapid decrease in price.

So how exactly did the hack happen? BitGo tweeted earlier today that they “found no evidence of a breach on any BitGo servers.”
Bitcoin 'Miners' Face Fight For Survival As New Supply Halves - Slashdot. SpzToid quotes a report from Reuters: On Saturday, the reward for [bitcoin] miners will be slashed in half.

Written into bitcoin's code when it was invented in 2008 was a rule dictating that the prize would be halved every four years, in a step designed to keep a lid on bitcoin inflation. From around 1700 GMT on Saturday, instead of 25 bitcoins up for grabs globally every 10 minutes, worth around $16,000 at the current rate BTC=BTSP, there will be just 12.5. That means only the mining companies with the leanest operations will survive the ensuing profit hit. "The most important thing is to be the most efficient miner," said Streng, the 26-year-old co-founder of German firm Genesis Mining, which has "mining farms" in Canada, the United States and eastern Europe, as well as in Iceland. "When the others drop out, that means that they leave the market and give you a bigger share of the pie.

The reward for mining Bitcoin was just cut in half. It’s Halvening!!!

Bitcoin just experienced a major milestone in its short little lifespan. The reward for mining a block (a block = a ledger of transaction data) was just cut in half from 25 bitcoins to 12.5 bitcoins. This means that assuming a price of $650 per coin, going forward miners will make ~$8,125 per block they mine, compared to $16,250 before the halving. But it’s ok!

This Week On The TechCrunch Bitcoin Podcast: A Reprise. Hey friends, and welcome back to a partially new episode of the TechCrunch bitcoin podcast, better known as TCBTC.

A few weeks back, this little show hosted Jason Rowley on the program, shooting video in the mix. However, due to production overlaps, we didn’t get the full audio version up. So, without further ado, here is our show with Mr. Rowley, in proper sonic format. If you can’t find the episode in your favorite podcast app, we apologize. With Jason we dug into the important bits of the block size question, and, of course, made him prognosticate where the price of bitcoin will land in a bit of time.

When Gavin Andresen and Mike Hearn released BIP101/XT last week, they emphasized the need for an increase to the Bitcoin block size to address concerns of transaction scaling as adoption increases. Instead, it has touched off a war in the Bitcoin community, dev teams, miners and mining pools. The latest news on the debate is the fact that BIP100 has been adopted by F2Pool, BitClubPool, and Kano.is with some other smaller pools joining. This movement represents a resounding 25% + of the network hash rate, with rumors swirling of more to follow.
Updated: Major Mining Pools Make a Stand Against Bitcoin XT Fork, Support for BIP 100 Grows. It has been little over a week since Mike Hearn and Gavin Andresen included Bitcoin Improvement Proposal 101 (BIP 101) into the alternative Bitcoin implementation Bitcoin XT. BIP 101 is designed to create a hard fork in the blockchain to allow for blocks of up to 8 megabytes, doubling every two years. Despite a major uproar on forums, chat rooms and in the media, not to mention a significant drop in bitcoin’s exchange rate, support among miners is minimal.

Bitcoin XT will need 75 percent of newly mined Bitcoin blocks to trigger a maximum block-size increase, but only some 1 percent of new blocks so far included such a message – all mined by Slush Pool. Moreover, it seems unlikely that the 75 percent threshold will be reached any time soon.
